This AD8318 module converts RF input at its SMA connector to a logarithmic DC output. It is for electronics users integrating a powered detector board into their own measurement circuit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e✅ \u003cstrong\u003eCompare signal levels in a bench project\u003c\/strong\u003e — A DC output changes with the applied RF input.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eConnect a suitable RF test lead\u003c\/strong\u003e — The SMA female input fits the stated connector interface.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eRead the output in your own circuit\u003c\/strong\u003e — Exposed output and ground pads provide connection points.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eMount the board in a project assembly\u003c\/strong\u003e — Corner holes provide physical fixing positions.\u003c\/li\u003e\n\u003cli\u003e✅ \u003cstrong\u003eBuild around a ready-made detector stage\u003c\/strong\u003e — The board combines the detector IC and supply-regulation circuit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAn RF-to-DC stage for your own measurement circuit\u003c\/h2\u003e\u003cp\u003eThe module is a detector stage, not a complete power meter or spectrum analyser. Supply it correctly, apply a suitable RF signal and measure the output with separate equipment. Establish the calibration for the actual frequency, board and signal range before interpreting a voltage as an absolute power reading.\u003c\/p\u003e\u003cp\u003eThe stated operating span is 1–8,000 MHz with a nominal −65 to +5 dBm input range. These figures are not a guarantee of equal accuracy or dynamic range at every frequency. The stated typical detection slope is −25 mV\/dB, with an approximately 0.5–2.1 V output range.\u003c\/p\u003e\u003cp\u003eOne AD8318 board is supplied. It requires a separate 7–15 V DC supply and a compatible readout or acquisition circuit. RF leads, attenuators, enclosure and test instruments are excluded.
